The Element3 300AH Pro Series lithium battery gives you the easiest AS3001 compliant installation on the market. The Pro Series features a battery enclosed in a sealed powder-coated steel box, with ventilation output to comply with AS3001 installation laws for lithium batteries inside the habitable area of connectable electrical installations. It also includes high & low temperature, high & low voltage and overcurrent protection, as mandated by AS3001.2:2022 Australian installation standards. Multiple mounting hole options provide ease of installation, and the Pro Series is stackable (2 units maximum per stack).

Boasting a compact design, this 300AH battery will fit in the same position as most 300AH batteries on the market. The high discharge BMS allows you to draw large loads from a single battery, making your system as cost-effective as possible with no need for multiple batteries.

The battery BMS delivers one of the safest lithium batteries on the market, with 3 temperature sensors – two internal battery temperature sensors plus a BMS MOSFET temperature sensor. The BMS monitors high and low temperature ranges. Also featuring individual cell voltage monitoring wires for each cell, protecting against high and low voltage parameters. The BMS also features overcurrent protection.

Key features include a 10% state of charge audible alarm that prevents over-discharge and protects battery life, ensuring maximum longevity from your lithium system. The durable powder-coated steel construction provides maximum protection and regulatory compliance for reliable performance in demanding applications.
